It is basically the Ubuntu LTS kernel. I run it on every amd64 system of mine. So, yes, I think it is better. If you use zfs, it definitely is.
Thank you for your advice and your help I am really appreciate that! I will try the proxmox sonn too
I have the same issue, but I'm a bit confused what grub has to do with that. Would it be possible to summarize what actual steps led to your success?
I've not changed anything with grub what-so-ever, but my boot disk isn't sda. It's sdb for an unknown reason.
I have messed up my grub somewhere between upgrading of a system and installing nvidia drivers. We have just verifying if grub is correct.
Look at the post #6 of this thread:
Make sure the the files in /etc/apt/sources.list and /etc/apt/sources.list.d/ refer to bullseye and not buster,
apt clean all
If that doesn't get it.
apt install linux-headers-5.16.0-0.bpo.4-amd64 linux-headers-5.16.0-0.bpo.4-common linux-kbuild-5.16
If it did not work for you, the sudo apt-get install linux-image-amd64 finally helped me.
